Natural selection is part of Darwin's theory of evolution saying that those individuals within a species that don't adapt well to their environment will eventually die off, while those that do adapt will continue on with future generations.
Facts About Darwin's Research
- Recently graduated from college, Darwin joined up with a British Navy mapping ship that was going on an expedition around the world.
- Darwin wasn’t the first scientist to study the idea of evolution; however, he was the first to come up with a workable theory about how, exactly, this evolution took place.
- Darwin's research focused on:
- The adaptation of a species in order to survive in various conditions
- The variation among individuals that caused them to live while others died
- The passing on of those advantageous traits
An example of natural selection are insects which are resistant to pesticides.

natural selection - Cultural Definition
A process fundamental to evolution as described by Charles Darwin. By natural selection, any characteristic of an individual that allows it to survive to produce more offspring will eventually appear in every individual of the species, simply because those members will have more offspring.
- The expression survival of the fittest was used to describe this process in the nineteenth century but is not favored by modern scientists.
